I saw my first two White-throated Needletails for this season this morning
while participating in a monthly bird survey at Eatons Crossing, SEQ.
They were following the upstream course of the South Pine River.  The
co-ords were S27 20'53.0" and E152 56'35.8'

Saddened to read that the status of WTNTs is now declared as vulnerable.

> G'day Bird Enthusiasts
> Stephen Garnett has just informed me that the WTNT has been declared
> Vulnerable.  Thank you all for helping to collect the data to make this
> declaration.  Here are the details:
> White-throated Needletail Hirundapus caudacutus caudacutus
> Listed in Australia as Vulnerable A2b+3b+4b
> Evidence has been presented in Tarburton (2014) that there has been a
> decline in the migratory subspecies exceeding 30%. This decline has been
> corroborated using a number of independent data sources. It has been
> attributed primarily to habitat loss in the breeding grounds. Only
> Criterion A can apply as the subspecies occurs over too large an area for
> Criterion B, is too numerous for Criteria C and D and has not been modelled
> in a manner suitable for Criterion E. The rapid decline has been occurring
> over a long period so this probably counts as a correction to the 2010
> Action Plan, but listing probably could not be justified for 1992 or 2000.
> At this stage only criteria A2b+3b+4b apply - declines of 30-50% in 3
> generations (25.5 years) based on an index of abundance appropriate to the
> taxon. The suggestion that the decline is caused by habitat loss, though
> likely, is still a little speculative to warrant A2c.
> As a result of sending my last Annual report on WTNT, Alastair Smith has

> fair I have dug out all group resources and hope I have not missed any.
> These are the number of observations from each source – and of course there
